1484579 Spectrographic analysis BLOCK ENG Inc 4 Dec 1974 [19 Dec 1973] 52454/74 Heading G2J Chemical species e.g. R.N.A. and D.N.A. are determined by staining them with a mixture of at least two chemically compatible dyes having differing binding energies for the various species and measuring the relative spectral intensities of at least two different wavebands. The dyes may be fluorochromes excited by U.V. light or an absorbtion method may be used. Acronol phloxine with either berberine sulphate or astrazone orange are suggested mixtures.
